Understanding Child Support and CRA Tax Rules in Ontario

If you are separating or divorcing in Ontario and have children, child support will be one of the most important issues to resolve. Alongside the legal considerations, it is essential to understand how child support is treated for tax purposes. Many clients are surprised to learn that child support has very different tax treatment than spousal support in Canada.

At Van Delft Law, we help parents across Ontario navigate child support agreements and orders, including how support impacts their taxes and government benefits. Here is what you need to know about the CRA’s rules on child support.

Child support payments are not tax-deductible for the payor and are not considered taxable income for the recipient. This rule applies to all child support arrangements made after May 1, 1997. It doesn’t matter whether the payments are made voluntarily, through a separation agreement, or by court order. The CRA’s position is clear: child support is tax-neutral for both parties.

For child support arrangements established before May 1, 1997, different rules may apply. In those cases, child support may still be taxable and deductible, depending on whether the agreement has been changed or replaced. If you are unsure about how your agreement is classified, it is a good idea to have it reviewed by a family lawyer who can clarify your rights and obligations under current law.

It is important to distinguish child support from spousal support, which is usually taxable for the recipient and tax-deductible for the payor. Problems can arise when a support agreement does not clearly separate child support from spousal support. If the agreement simply states a single monthly amount for “support” without indicating how much is allocated to each, the CRA will treat the entire amount as child support. This means the payor will lose the ability to deduct any portion of the payment, even if it was intended as spousal support.

To avoid this issue, make sure your support agreement or court order specifies how much is for child support and how much is for spousal support. At Van Delft Law, we assist clients with carefully drafting or reviewing support agreements to ensure they comply with CRA rules and protect their financial interests.

If child support payments are not being made on time, or if they are inconsistent, the recipient may need to take enforcement steps. While the CRA will not get involved in enforcing support payments, Ontario’s Family Responsibility Office (FRO) can assist in collecting overdue amounts. However, it is important to note that only amounts actually paid qualify under the CRA’s definition of child support. Payments that are missed or in arrears are not considered when calculating benefit entitlements or tax credits.

Another important consideration is how child support affects your eligibility for tax credits and benefits. Your marital status and living arrangements can impact your entitlement to the Canada Child Benefit, the GST/HST credit, and other tax credits such as the eligible dependant credit. When you separate, you must notify the CRA and update your marital status to avoid being overpaid or underpaid on benefits.

If you are the recipient of child support and you share custody of your children, you may still be eligible to claim certain tax benefits. In shared custody situations, it is sometimes possible for both parents to claim the eligible dependant credit in alternate years, provided that each has the child in their care at least 40 percent of the time and both contribute to the child’s support.

If you are paying or receiving child support, make sure your tax return accurately reflects your situation. Although the payments themselves are not taxable or deductible, your eligibility for other tax credits depends on up-to-date and accurate information.

At Van Delft Law, we help clients across Ontario make sense of the legal and tax implications of child support. Whether you are establishing a new agreement, dealing with enforcement, or responding to a request for variation, we are here to guide you through the process.
